16. Roosevelt Avenue Terminal Station
Before the Great Depression, a Second System was planned for the IND line to connect the Rockaways and midtown Manhattan. A full station and tracks were installed in Queens that were to connect to the Roosevelt Avenue-74th Street stop but were never used. You can see remnants where these tracks now dead-end at 78th Street. In addition, many active stations have unused levels and platforms which we explore in a follow-up piece here.
